When I bought my AE111 it had Toda 264 9.0mm cams on stock springs. I rebuilt the engine with new Toda springs though.

Hello
Did you ever do a dyno test?

Are you concerned with coil bind or valve float?
It also depends on how aggressive the cam profile is for valve float.
I assume based on this question you are looking at buying some new cams? If so just bite the bullit and get some uprated supertech springs and run which ever cam spec you like.
